These projections (Z are preferably formed with their opposite sides or edges (1* tapering toward each other and disposed in planes substantially parallel to lines drawn through the center of said deflector and midway between said projections. The inner frontedge fl is much narrower than the outer, and preferably inclines downward from the top face of the projection toward the face of the deflector, upon which the water strikes. As the stream of water is reflected from the upper face of the deflector the projections (Z cut the same up into small streams, which are reflected or thrown upward from the upper face of the deflector, and the water is thereby spread out so as to cover a large surface. To further aid these projections in spreading or dist-rilniting the stream of water or other liquid, the outer edges thereof are provided at their top with the slight projection or roll (1, which forms a stop for the water striking against the top faces of said projections and causes the same to be rolled or spread from the top thereof.

Arranged alternately with the projections d are the projections D, of tapering form, with the base slightly larger than the top for the purpose of forming a wedge, which shall cut up the stream of water, which would otherwise be distributed from between the projections 1)" without being cut up or spread thereby. Upon reference to the drawings it will be noted that the projections D are of less length than the former projections (Z and it will be understood that this arrangemel'it greatly aids the perfect operation of my improved deflector.

The top face of the deflector is preferably provided with a recess D, which is of suflieient size to receive the valve Z) of the dropbolt B and cause the top face of the same to be on the same line or plane as the upper face of the deflector, thus forming a smooth surface,whichwi ll reflectt-he water u pward evenly against the distributing projections provided thereon. The top face of the deflector and valve of the drop bolt are preferably (lisposed in a horizontal plane; but it will be understood that said plane might be made concaving without changing the operation of my deflector.

'lt will be understood that I do not limit my deflector to its use in the precise form of fireextinguisher herein described, since this is only one form of construction, which has been described merely for the purpose of showing the operation of the deflector, and the same might be substituted by one of different construction, whereas the operation of the deilector would be precisely the same. It will also be understood that considerable change maybe made in the relative construction and arrangement in the described form of deflector, which is merely the preferable construction of the same, and might be greatly altered in the relative construction and arrangement of its parts without departing from the spirit of my invention.

I am aware of the devices set forth in the patents to J. Hill, No. 329,311, issued October 27, 1885, and to \V. Neracher, No. 3(il,175, issued April 20, 1887, and 1 do not herein claim the construction of deflector set forth in said patents.

llaving thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The herein-described deflector for automatic sprinklers, the same consisting of a plate, and projections d rising above said plate and formed with an upper face, and projections (Z elevated above said upper face, substantially as specified.

2. The herein-described deflector for automatic sprinklers, the same consisting of a plate, project-ions (Z rising above said plate and formed with an upper face, and projec' tions d5 above said upper face, and a second series of projections of less length than the former series alternately arranged with said former series, substantially as and for the purpose set forth.

In testimony whereof I have hereunto signed my name in the presence of two attesting witnesses, at Syracuse, in the county of Onondaga, in the State of New York, this 23d day of February, 1889.
